    Study Notes

    Software Testing Objectives

    • The primary purpose of smoke testing is to ensure that the most critical functionalities of the software application are working as expected.

    Usability and Business Needs

    • Usability testing primarily focuses on understanding how users interact with the software application to identify areas for improvement.
    • Requirements-based testing ensures that the software meets business needs and requirements.

    System and Regression Testing

    • The main objective of system testing is to evaluate the software application as a whole to ensure it meets the specified requirements.
    • The purpose of regression testing is to ensure that changes made to the software application do not introduce new bugs or affect existing functionality.

    Functional and Non-Functional Testing

    • Functional testing focuses on verifying the functionality of the software application according to requirement specifications.
    • The primary difference between functional testing and non-functional testing is that functional testing focuses on what the software does, whereas non-functional testing focuses on how the software performs.

    Integration and A/B Testing

    • The primary purpose of integration testing is to ensure that individual software components work together seamlessly as a single unit.
    • The main purpose of A/B testing is to compare two versions of a software application to determine which one performs better.

    Stress Testing

    • Stress testing is particularly important when the software application is expected to handle a large volume of users or data, ensuring it can perform under extreme conditions.
